About AI Training Work

AI training is the human side of building artificial intelligence. Expert contributors review model outputs, answer complex questions, generate high-quality examples, and evaluate whether responses are accurate, clear, and scientifically sound.

This work is fully remote and often flexible, making it possible to contribute around other commitments while directly influencing the development of cutting-edge AI systems.

The Role

OpenTrain AI is seeking a Physics Expert specializing in atomic, molecular, and optical physics, with a focus on the optical properties of materials. You will provide expert input for AI training through adaptive spoken interviews and related audio labeling, question-answering, evaluation, and text-generation workflows.

The engagement is part-time and fully remote, with candidates welcomed worldwide. The expected commitment is 5 to 10 or more hours per week while remaining under 20 hours per week overall. The project is expected to run for 1 to 3 months.

• Contractor and part-time engagement
• Fully remote and open worldwide
• Expected commitment: under 20 hours per week
• Typical schedule: 5 to 10 or more hours weekly
• Expected project duration: 1 to 3 months
• Compensation: $100 to $200 per hour
• Working language: English

What You’ll Do

You will participate in adaptive, spoken AI interviews by responding to one question at a time. Your answers should be clear, concrete, and grounded in legally shareable research or project experience.

The work combines advanced physics subject-matter expertise with structured AI evaluation and content-generation tasks.

• Provide expert insights on AMO physics and optical properties of materials
• Review and discuss ab initio configuration interaction methods for calculating polarizability in atomic systems
• Analyze atomic-structure calculations involving Yb-171 and Yb-174 isotopes
• Identify and distinguish sigma and pi transitions in relevant atomic spectra
• Explain the physical principles underlying sigma versus pi transitions
• Complete audio labeling, question-answering, evaluation-rating, and text-generation workflows
• Communicate scientific reasoning clearly in spoken and written formats

Requirements and Preferred Qualifications

This is an expert-level opportunity for a physicist with substantial knowledge of AMO physics, optical properties of materials, and atomic-structure computation. An advanced degree is preferred, though equivalent experience may also be considered.

You must be fluent and comfortable working in English. Prior AI-training experience is not required, but experience with audio labeling workflows and AI-oriented question answering or evaluation is relevant to the project.

• Advanced degree, such as an MS or PhD, in Physics, or equivalent experience
• Focus on AMO physics or optical properties of materials
• Experience with ab initio quantum chemistry calculations
• Specific experience using configuration interaction approaches to calculate polarizability
• Deep understanding of atomic-structure computation techniques for Yb-171 and Yb-174
• Ability to identify and explain sigma versus pi transitions in atomic contexts
• Experience with audio labeling workflows
• Experience with question answering, evaluation rating, and text generation tasks
• Fluent English proficiency and comfort communicating in English
• Ability to provide clear, structured scientific explanations

Who Should Apply

This role is suited to an AMO physicist, atomic-structure researcher, quantum chemistry specialist, or related expert who can explain sophisticated concepts accurately and accessibly. It may be especially relevant to professionals or researchers working with ytterbium isotopes, polarizability calculations, spectroscopy, or optical material properties.

Applicants should be prepared to discuss only research and projects they are legally permitted to share, and to contribute reliably within a flexible part-time schedule.

• AMO physicists and atomic-structure researchers
• Quantum chemistry experts familiar with configuration interaction methods
• Researchers experienced with ytterbium isotopes and atomic spectra
• Specialists in polarizability or optical properties of materials
• Experts who communicate complex scientific ideas clearly
